Q. How do I open port 80 (Apache Web Server) under Red Hat / CentOS / Fedora Linux?
A. The default configuration file for iptables based firewall under RHEL / CentOS / Fedora Linux is /etc/sysconfig/iptables. Open this file using a text editor such as vi:
Linux Open Port 80 (http)
# vi /etc/sysconfig/iptables
Append rule as follows:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
Save and close the file. Restart iptables:
# /etc/init.d/iptables restart

I tried this and restarted the ipchains with service iptables restart
but it will still not work.
any ideas?
Thanks for this. Being used to debian/ubuntu I’d forgotten where to go when setting up a CentOS box.
@gabriel – you might want to try moving the rule further up in the file. I put it as the last rule but that didn’t work. Moving it further up (in particular before “-A RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited”) seemed to do the trick.
